David, I found that free memory can have some SERIOUS effects on the
speed of the Finder.  I was playing 'stress-test' and opened a set of
applications such that there was less than 100K of memory remaining.
When toggling back to the Finder (via the application menu), there was a
LARGE delay in the toggle itself, followed by the kind of 'one folder at
a time' redraw that you have seen.

Quitting a single application to free up more memory resulted in a
huge speed increase.  It looks like the Finder wants some amount of
memory left available at all times (for best performance anyway).
